TIMING DEVICE Filed June 12, 1934 ATTORNEY Patented Apr. 14, 1936 UNITEDSTATES PATENT OFFICE 1 Claim.

This invention relates to a timing device for games and is especiallyadapted for use by a timekeeper of a boxing match or prize fight or maybe used for training persons to different periods of time and has forthe primary object the provision of a device of the above statedcharacter whereby playing or fighting periods, rest periods and warningperiods preceding playing or fighting periods within the rest periodsmay be accurately given by the timekeeper through the aid of anelectrically actuated time controlled mechanism.

Another object of this invention is the provision of signal means forindicating periods of time of one second each at any time or within theplaying or fighting periods so that an accurate count may be made when aperson is down or out in the fighting ring.

With these and other objects in view this invention consists in certainnovel features of construction, combination and arrangement of parts tobe hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had tothe following description and accompanying drawing, in which Figure 1 isa front elevation illustrating a timing device constructed in accordancewith my invention.

Figure 2 is an end elevation illustrating the same.

Figure 3 is a diagrammatical view illustrating the wiring diagram of thedevice.

Referring in detail to the drawing, the numeral I indicates a base onwhich is mounted an electrically actuated time clock 2, the dial ofwhich is graduated for sixty seconds and over which is moved a secondhand 3 and a minute hand 4. The electric motor 5 of the time clock 2 iselectrically connected in an electric circuit composed of feedconductors 6 and The conductor 1 has connected thereto a main controlswitch 8 for starting and stopping the clock 2. The motor 5 drives asignal control mechanism 9 mounted on the base and consists of a toothedwheel |ll rotatably supported and connected to the motor 5 by a sprocketchain and gearing so that the toothed wheel rotates in the direction ofthe arrow in Figure 1 and makes a complete revolution each minute duringthe operation of the clock 2. Insulation blocks H are arranged betweenthe teeth of the wheel I!) and the teeth are engaged 'by a contact l2.The wheel l also carries a contact pin l3 to engage with a contact I4 oneach revolution of the wheel Ill. The contact pin l3 is eccentricallymounted on the wheel and moves in the path of a rotatable contact deviceIS in the form of a star Wheel having contacts l6, l1, I8, and iii. Therotatable contact element I is journaled on the base and is given a stepby 5 step movement by the contact pin l3 during the rotation of thewheel Ill. Mounted on the base are electric lamps 20 and 2|, the lamp2|! being of one color and preferably green while the electric lamp 20is of another color and preferably 10 red so that they can be easilydistinguished from one another at a distance. The electric lamps 20 and2| provide signals and if desired the lamps may be substituted for byother forms or types of signals. The electric lamp 29 is connected tothe contacts Iii to Hi by a conductor 22 and the electric lamp is alsoconnected to the conductor 7 by a conductor 23. The wheel H] isconnected to the conductor 6 by a conductor 24 and a wiping element 25that rides against the Wheel NJ during the rotation thereof. The contactI4 is connected to one pole of a double control switch 26 by a conductor21 and the contact I2 is connected to the other pole of the switch 26 bya conductor 28. The switch 26 is connected to the electric lamp 2| by aconductor 29 and is also connected to the conductor 1 by a conductor 30having a switch 3| preferably in the form of a push button. Theconductor 36 between the electric lamp 2| and switch 3| has connectedthereto a 30 conductor 32 which is in turn connected to a switch 33 andthe latter is connected to the conductor by a conductor 34.

The switches heretofore referred to are mounted on the base 1, as shownin Figure 1, in convenient reach of the timekeeper.

The green electric lamp 20 is for the purpose of indicating fightingperiods and rest periods in a boxing match or prize fight while the redelectric lamp is for the purpose of indicating seconds 40 and also a tensecond signal preceding the fighting period within the rest period. Therotatable contact element l5 in the form of a star wheel in cooperationwith the contact pin 3 controls the circuit to the electric lamp 26 insuch a way as to indicate a signal of the beginning of a round orfighting period of three minutes and to indicate the end of tliefighting period and then indicate the rest period of one minute betweensaid fighting period and the following fighting period of three minutes.The ten second signal preceding the fighting period is given by the redelectric lamp 2| by the timekeeper positioning the switch 26 to closethe circuit through the conductor 21, contact I4 and contact pin l3.

It is to be understood that the timekeeper thus positions the switch 26within the rest period so that ten seconds will elapse between thelighting of the electric lamp 2| and the lighting of the electric lamp2!) through the rotatable contact element l5. During the fighting periodthe timekeeper throws the switch 25 to include the contact 12 in circuitwith the electric lamp 2| and should a fighter be knocked down or outduring the fighting period, the instant the fighter falls the timekeeperactuates the push button 3| and the electric lamp 2| is then illuminatedeach second so that ten seconds can be easily counted in determiningthat the fighter is ofiicially out and the fight ended thereby. It is tobe understood that when the switch 26 is positioned to complete thecircuit to the conductor 2'! the switch 33 is closed and that during theentire operation of the device the main switch 8 is closed.

The clock 2 besides providing a power medium for the actuation of thesignal control mechanism 9 also provides for the timekeeper a stop clockmechanism in that its operation can be controlled through the actuationof the main switch 8.

Having described the invention, I claim:

In a timing device an electrically actuated clock and a switchcontrolled electric circuit for the clock, a toothed metal wheel havinginsulator strips between the teeth thereof and means between the clockand wheel for turning the wheel, a metal pin projecting from the wheel,a star gear of insulating material to be turned when contacted by thepin, contacts between certain of the opposed teeth of the star gear tobe engaged by the pin, a lamp, a conductor between the lamp, thecontacts and one of the conductor wires of the circuit, a wiper contactengaging the toothed wheel and wired to the second conductor of thecircuit, a spring contact in the path of contact with the pin, aconductor wire leading therefrom, a brush switch in wiping engagementwith the periphery of the wheel, a conductor therefor, a switchswingable to engage with the terminal ends of each of said last namedconductors, a conductor wire leading from said switch, a lamp connectedto the said wire, and connections from the lamp to one of the conductorwires and including manual switches therein.
